Fall of the Empire (trailer below the break as a reminder) is on it's way, but Silly Filly Studios has an update up on Tumblr about their pony animation projects as a whole. It sounds like the new Content ID system that Youtube rolled out (to the dismay of let's players and parody makers alike) is having a negative effect on their projects. Apparently some of their videos are being claimed automatically just for having ponies in them, an issue Youtube content creators are having in just about every topic.
They plan to shift into more original content, something quite a few pony animation teams are doing. Go wish them luck over on Youtube! Expect Fall of the Empire some time in the future when it is officially complete.
